DETROIT - The New York Yankees are optimistic that ace Masahiro Tanaka can return to help them in the pennant race in September after watching his performance Thursday morning in his first big test.

Tanaka used all of his pitches without any signs of discomfort in a 49-pitch simulated game. He has been sidelined since July 8 with a partially torn ulnar collateral ligament in his right elbow.

Yet, instead of opting for Tommy John surgery, Tanaka decided to rehab his elbow and try to return in time to get the Yankees into the postseason.

"I don't see anything to believe he won't take the next step,'' Yankees manager Joe Girardi said. "I am optimistic."

Tanaka, who says he still feels rusty, is expected to make at least two more starts in simulated games before rejoining the rotation. If he remains healthy, he could be in line to make at least three more starts in September in hopes of helping the Yankees avoid back-to-back seasons without making the playoffs.

The Yankees entered Thursday's game against the Detroit Tigers six games behind the Baltimore Orioles in the American League East, and 2 ½ games out of the second wild-card spot.

"I'm still not there yet," Tanaka said. "I still have some work to get ready.

"I think I'm being cautious more than excited."

The Yankees had trouble controlling their excitement, firmly believing that Tanka, in whom they invested $175 million, will be back.

"He was good," Girardi said. "He threw all of his pitches. I didn't see him favoring anything, and that's a good sign.
